This document provides an analysis of server virtualization savings over a 5 year period from 2013-2017. It summarizes the configuration of physical and virtualized servers, assumptions made, and projected savings in server hardware, power/cooling and storage by transitioning to a virtualized environment. Key metrics included are the reduction in number of servers from 400 physical to 22 virtual hosts, savings of $998,000 on server hardware and $915,388 on power/cooling costs by transitioning to virtualization.

Server Impact On Server Storage: Key Assumptions
Key features in vSphere such as High Availability and vMotion are enabled by shared storage between hosts. For customers who will not be implementing
physical a shared storage solution, a new software solution from VMware, the vSphere Storage Appliance (VSA), transforms cheaper internal host storage
(up to 3 hosts) into a single shared storage resource.
Ideal for customers planning to virtualize smaller environments with vSphere Essentials+.
